Loop The Loop Starring Corky (1M40.20) Location: 56-1C Concept/Purpose: Conservation of Energy Procedure/Explanation: The loop the loop is a small brass section of roller coaster with a small brass cart. To demonstrate conservation of energy the cart can be started at either the high or low end of the track. Starting at the high end gives the cart enough energy to make it around the loop while starting at the low end does not give it enough energy. To demonstrate centripetal force the cart is released from the high end. While traveling through the loop, the cart does not fall off the track because of its centripetal acceleration. A special volunteer is available upon request: Corky (a large cork) will ride on top of the cart, and more often than not, even surviving.
